Tower
CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the problem.
The Dell Precision 3630 Tower contains both volatile and non-volatile (NV) components. Volatile components lose their data immediately
after power is removed from the component. Non-volatile (NV) components continue to retain their data even after power is removed
from the component. The following NV components are present on the Precision 3630 Tower system board.

CAUTION: All other components on the system board lose data if power is removed from the system. Primary power loss
(unplugging the power cord and removing the battery) destroys all user data on the memory (DDR3, 1067 MHz). Secondary
power loss (removing the on-board coin-cell battery) destroys system data on the system
conguration and time-of-day
information.
